Deformity of right orbit due to bone disease

This code signifies an abnormal shape or structure of the bony socket surrounding the right eye, specifically caused by an underlying disease affecting the bone itself. This deformity can impact ocular function, vision, and the aesthetic appearance of the eye and surrounding structures.

Apply this code when documentation clearly indicates a structural abnormality of the right orbit resulting from a bone pathology, such as fibrous dysplasia, Paget's disease, or osteomyelitis. The physician's notes should specify the laterality (right orbit) and the causative bone disease.

• Ensure the documentation specifies the right orbit; left or bilateral deformities require different codes.
• Always code the underlying bone disease first, as it is the etiology of the orbital deformity.
• Distinguish from orbital deformities due to trauma, congenital anomalies, or other non-bone disease causes.
